  Abstract

We adopt cognitive radio for tactical trunk systems to solve the shortage of radio spectrum. To set up a channel, cognitive radio systems need spectrum sensing over many frequency bands and especially any two nodes should rendezvous on a certain frequency within a short time. If they rendezvous on a low frequency that propagates well, the others nearby may not use this frequency that is essential for their geographical features. Therefore, we propose a geolocation protocol where a node senses effective frequency bands considering its geographical and environmental conditions. From simulation results, we confirm that our protocol enhances the probability of network setup while reducing the setup time, compared to existing ones.
